Title: Improvements in or relating to time stamp machines
IPC: G07C1/06
Filed: 1924-06-30
Abstract: 239,952. Lyons & Co., Ltd., J., and Goddard, A. June 30, 1924. Time printing.-In a time-printing stamp of the kind in which the ticket to be stamped and the type are pressed together by an electromagnet, the magnet is so disposed that the direction of the resultant of its forces passes through the ticket and substantially at right angles thereto. The stamp may be constructed by modifying an ordinary manually operated machine in which a platen 2 carried by a pivoted arm 5 is manually depressed to print the ticket against type 1 set by clock mechanism in the base 4. The platen 2 which is usually secured directly to a plate such as 10 pivoted, by a portion 13, in the arm 5, is preferably mounted on an intermediate plate 9 yielding!y carried by springs 11 and bolts 12 from the plate 10. The usual knob provided on the part 13 for manual operation is removed, and an electromagnet 3, mounted in a frame 25 bolted to the base 4, is arranged so that a striker 17 carried by its armature 16 engages the top of the member 13. The leads 18 of the magnet are connected through a switch 20 to a wall plug 21, so that upon closing the switch by depression of a button 19, the striker 17 is depressed to actuate the arm 5. A casing 29 surrounds the electrical part of the device. The platen is held normally out of contact with the type 1 in the usual manner by a spring-urged arm 8 engaging a screw 7 carried by the arm 5. The printing is effected through an ink-ribbon.

Abstract: 417,885. Spray carburetters. PIAT, J. M., 23, Cours Tolstof, Villeurbanne, Rhone, France. May 31, 1933, No. 15726. Convention date, May 31, 1932. [Class 7 (iii).] A piston valve 20 is moved by a lever 25 transversely across an air passage 33, Fig. 4, the lower end of the piston having borings 21, 22 adapted, in the closed position of the piston, to cover fuel nozzles 16, 17 of which 16 is shorter than the others and arranged coaxially with the piston. The nozzles are fed from a chamber 11, Figs. 1, 2, which receives fuel from the float chamber 1 through an orifice 10 in a tube 6 and one of a number of orifices c in a rotatable tube 9 within tube 6. The tube 9 is rotatable through an arm 15, with spring-catch 14, to bring a particular orifice to register with orifice 10. A pair of tubes, similar to those just described -and arranged parallel thereto, are employed to conduct fuel to a starting and slow-running nozzle 32, Fig. 4, on the engine side of the throttle valve, the inner tube being rotated to cut off the fuel when the main nozzles are in action. The fuel chamber 11 communicates with the atmosphere through ducts 49, Fig. 2, and tubular member 51 provided with an inlet 52 controlled by a rotatable spring- loaded ring 53 and also with an inlet 51 controlled by a suction-actuated spring-loaded ball valve 60. The casing 5<1> of the piston valve 20 rests on a projection from the float chamber, the parts being held together by a screw 19 and cap 19<1>. Against a flat face of casing 5<1> a plate 47, Fig. 14, is adapted to be held by a screw 43, the plate being adjustable vertically over studs 42, 44, to vary, by its lower edge 45 the air inlet, as well as the position of a nozzle 46 for the admission of water supplied through a flexible tube 48, the atomization of the water being assisted by an air inlet orifice 47. The central nozzle 16, Figs. 1, 3, is enlarged at its base to be bored transversely at 26, 27, the smaller bore 26 facing the air inlet. Air may be admitted to the piston bore 21 surrounding nozzle 16 at starting by an adjustable bored screw 35 controlling an aperture 36 in the lower end of the piston. When the piston 20 is raised slightly, Fig. 4, a groove 37 places the bore 21 in communication with the suction passage in which case air is drawn through the transverse bores 26, 27, Fig. 3, to extract fuel from the nozzle bore. During this period, air is sucked downwardly through nozzles 17 to chamber 11 to supplement air entering by passages 49.

Title: Process for the manufacture of mixed alkaloid salts
IPC: C07D451/10
Filed: 1927-06-14
Abstract: 273,279. Chemische Fabrik auf Actien, vorm. E. Schering. June 26, 1926, [Convention date]. Mixed salts of solanaceous alkaloids with dibasic acids are prepared by combining the components in the presence of a solvent and then removing the latter by evaporation in vacuo without raising the temperature. Acids specified are camphoric, malonic, phthalic, meconic, tartaric, saccharic, terephthalic, succinic, sulphuric, and sulphurous acids. The products possess therapeutic properties. According to the examples, (1) solutions of scopolamine and hyoscyamine in n-sulphuric acid are treated in admixture with barium camphorate or phthalate, filtered and evaporated to dryness in vacuo, leaving scopolamine-hyoscyamine camphorate or phthalate; (2) atropine-scopolamine tartrate or succinate results when an alcoholic solution of scopolamine, atropine and tartaric or succinic acid is dried in vacuo; the malonate is similarly obtained from an ethereal solution of the components, and the sulphate and sulphite from aqueous-alcoholic solution; (3) hyoscyamine is dissolved in an aqueous solution of scopolamine meconate and evaporated in vacuo, leaving the syrupy hyoscyamine,-scopolarnine meconate; the terephthalate is prepared by the same way. Specification 269,498 is referred to. The Specification as open to inspection under Sect. 91 (3) (a.) is not restricted to solanaceous alkaloids and describes the use of polybasic acids, of which phosphoric acid is given as an example. This subject-matter does not appear in the Specification as accepted.

Abstract: 340,918. Wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Hansell, C. W., Port Jefferson, Long Island, New York, U.S.A.). May 22, 1930, No. 15844. Convention date, June 20, 1929. [Class 40 (v).] The natural frequency of a piezo-electric crystal is varied by variation of the pressure of the medium surrounding it. The crystal 2, Fig. 1, has bevelled ends and is supported by fork-shaped members 16, 18 between electrodes 4, 6 so as to leave equal air-gaps 8, 10 of a natural period slightly different from that of the crystal between the latter and the electrodes, and pressure-waves are propagated through the gaps from an electromagnetically vibrated diaphragm 28 arranged at the end of a conduit 24 leading to the device. An outlet conduit 26 of exponential form prevents the reflection of the pressure-waves back across the surfaces of the crystal. The frequency-variation may be in accordance with speech currents supplied to the electromagnetic vibrator 30, and the crystal used to frequency-modulate a carrier wave, or the device may be used as a frequency wobbler. In a modification, Fig. 2, out-of-phase pressurewaves are produced by the vibrating piston 38, in the air-gaps 42, 44, between the crystal 34 and the conduit 32, which are of such a length as to give columns of air whose natural periods are slightly greater and slightly less, respectively, than the natural period of the crystal.

Abstract: 529,339. Automatic control systems. MAIHAK AKT.-GES., H. May 30, 1939, No. 15880. Convention date, June 7, 1938. [Class 38 (iv)] Reportioning mixtures Air supply to a furnace is adjusted towards scarcity when no CO is present in the flue gases and vice versa, the con trol being dependent or means sensitive only tc CO. The former adjustment is preferably slow and the latter rapid Any CO indicator may be employed. As shown, two like catalytic resistances 9, one of which is shielded from flue gas, are placed in the flue and arranged in a Wheatstone bridge sc that a relay 10 may close its contacts when CO is present in a proportion determined by adjustment of the remaining bridge arms. A motor 17 continuously drives friction clutch members 27, 28 at very different speeds in opposite directions and a spring 14 effects driving engagement between the slow running member 15 and a shaft 20 to produce closing movement of an air throttle 2 until the relay 10 responds whereupon the spring 14 is overcome and rapid reverse movement of the valve occurs. The drive may pass through a differential gear which by a rough adjustment of the throttle 2 may be effected automatically by means 7 depending upon coal burnt per unit of grate area. This rough adjustment of air supply may be made by other means. Other means of producing slowing movement of the valve may be used, such as selective control of two oppositely running motors.

Title: Improvements in or relating to drawing synthetic yarn
Inventor: CULPIN MICHAEL FRANK
IPC: D02J1/22
Filed: 1963-04-24
Abstract: 995,577. Drawing synthetic yarns. BRITISH NYLON SPINNERS Ltd. April 10, 1964 [April 24, 1963], No. 16092/63. Heading B5B. Synthetic yarn having occasional knotted joints is drawn in the solid state by forwarding said yarn from one or more feed rolls to one or more draw rolls revolving at a greater peripheral speed than said feed rolls, the yarn passing round a snubbing pin on its way from the feed rolls to the draw rolls, slowly lengthening the yarn path between the feed rolls and snubbing pin by conventional mechanical means prior to the approach of a knot and by the same means suddenly releasing the reserve of yarn thus accumulated by allowing the yarn to return to its original unlengthened path just before the knot reaches the drawing zone. Yarn which may be so drawn includes stereospecific polypropylene, polyethylene terephthalate polyacrylonitrile, polyethylene and polyamides, especially polyhexamethylene adipamide yarns of 800 denier or over. In Fig. 1 the yarn path between idler pulleys 5 and 6 is lengthened by rotating the disc 1 clockwise, and drawing action is temporarily suppressed by allowing the disc to turn back anti-clockwise until the yarn assumes the shortened path shown by the broken line 7. In Fig. 2, the yarn path between idler pulleys 9, 10 is lengthened by raising the plunger 7. The operation of Figure 3, which has a triple plunger, is similar. In Fig. 4 yarn path is lengthened by lowering the pivoted arm so increasing the distance between the pulleys 22, 23 and pulleys 19, 20, 21. In Fig. 5, turning the peripherally grooved eccentrically mounted disc 25 varies the path of the yarn. In Fig. 6, yarn path is varied by raising and lowering the spindle 30 on which is mounted a truncated cone 29. All forms of apparatus may be operated manually, or preferably, automatically, in conjunction with knotdetecting devices. Specification 956,992 is referred to.

Abstract: 932,172. Control of A.C. motors; controllers. S.A. DES ATELIERS DE SECHERON. May 6, 1960 [May 28, 1959], No. 16144/60. Class 38 (3). The voltage applied to a traction motor 1 during starting is determined by a tapped transformer 2 associated with a voltage regulator 3 and a vibrating relay 5, the relay being controlled by a self-excited transductor 4 acting as a pulse generator. The periods of the pulses decrease as a function of the difference between the motor current and a fixed reference current, the latter representing the maximum starting current of the motor. Thus, the notching-rate of the transformer is high when there is a large current-difference, and is low when the motor current approaches its maximum value. If the current exceeds the prescribed maximum value, the notching operation is suspended. The transductor may have a control-current winding, a polarizing winding, and a further input winding which is energized in accordance with the output voltage of the transductor. A supplementary control winding is provided for rapidly reducing and increasing the output of the transductor when the relay is energized and de-energized respectively.

Abstract: 1469333 Mixing and agitating fluids ITT INDUSTRIES INC 11 April 1974 [19 April 1973] 16220/74 Heading B1C [Also in Division F4] Unwanted water is got rid of by entraining it in an air stream. The entrainment means forms part of a self-contained air conditioner of the kind having an internal cooling heat exchanger, an outside condenser heat exchanger and means respectively blowing an internal and an outside air stream each over its respective heat exchanger. The unwanted water is water which has condensed on the cooling heat exchanger. The water collects in a drip tray, is delivered to a sump, and from there is entrained into the outside air stream and directed upon the condenser heat exchanger where evaporation into the atmosphere takes place. Fig. 1 shows a side view of the outside heat exchanger 18 with a centrifugal blower 11 blowing an air stream 14 thereover. The water 16 has collected in a sump area 34 next to the wall 17 of the blower 11. A device 15 enables the water to be entrained in the air stream 14. Figs. 3 and 4 show front and plan views of the device 15. The device 15 comprises a tube 22 which projects into the air stream 14. The angle of the tube opening 26 relative to the air stream 14 causes aspiration through the tube. The device 15 also includes a vane 24 which diverts some of the air from stream 14 through an opening 35 into the water. In addition, air flow 36, Fig. 3, derived from ambient air enters the device 15 through apertures 25 beneath lower edges of side walls 23 of the device. The air flowing through opening 35 and apertures 25 entrains water droplets. The resultant air stream 27 is ejected into the air stream 14.

Title: Process for the preparation of esters of gallic acid with aliphatic alcohols containing at least 7 carbon atoms
IPC: C07C69/88
Filed: 1949-06-20
Abstract: Gallic acid esters are made by heating the acid with an aliphatic alcohol containing at least 7 and preferably not more than 18 carbon atoms in the presence of an esterification catalyst, in a medium containing a non-polar inert solvent which distils azeotropically with water, and removing the water produced by the reaction by azeotropic distillation as the reaction proceeds.  Solvents specified are benzene, toluene and xylene and temperatures of above 150 DEG C., preferably 180-200 DEG  C., are advantageous.  Preferred catalysts are those soluble in the medium, such as aryl sulphuric acids, e.g. p-toluene and b -naphthalene sulphonic acids.  Preferably the reaction is started with an excess of alcohol and effected in a continuous fashion.  After the mixture has become homogeneous more gallic acid is advantageously added, the required quantity of this reagent thus being added in portions.  Advisably inert gases such as CO2 are passed through the reaction mixture.  In examples, gallic acid is reacted with (1) lauryl alcohol in xylene solution with b -naphthalene sulphonic acid; (2) n-octyl alcohol in benzene solution with sulphuric acid; and (3) n-octyl alcohol in toluene with b -naphthalene sulphonic acid to give the corresponding gallates.
